How to Change a Toyota TPMS A TPMS,or Tire Pressure Monitoring System,is a
sensor that is often housed in the tire's valve stem. The Transportation Recall
Enhancement,Accountability,and Documentation (TREAD) Act stated that all
vehicles made after 2008 must be be fitted with a TPMS,which alerts a driver
when a tire has low pressure. The device measures tire pressure and
temperature,then transmits this data to your tire pressure monitor ECU/receiver.
However,sensors can fail due to any number of reasons including mechanical or
electrical failure. You must take care while attempting to replace your
TPMS-equipped tire or you could risk interfering with or damaging the sensor.
Things You'll Need Crowbar Replacement TPMS Bartec Wheelrite TECH400 tool Jack
Support stands Penetrating oil Tire iron Pliers Instructions 1. Take your car to
a certified technician,who will use a Bartec Wheelrite TECH400 tool to determine
if your sensor needs replaced,and also pinpointing the nature of the problem Auto Code Scanner. 2. Buy a replacement
sensor-containing valve stem that is configured for your Toyota. To cut down on
costs,try purchasing a replacement sensor from aftermarket sources. 3. Raise
your car in the air using a jack and support stands. Remove your tire by
spraying its lug nuts down with penetrating oil then using a tire iron to remove
the nuts. 4. Relieve the tire pressure by unscrewing the valve stem cap to let
air out. The valve stem is a metallic valve that sticks out from the tire.
Next,lay the tire on the ground and use a crowbar to break the beads,or seal
between the wheel and tire. Pry the tire from the wheel with the crowbar. 5.
Soak and lubricate your replacement valve stem in some liquid dish soap,then
slide it into the hole in the tire vacated by the old valve stem. The valve will
seal itself maxitpms. Seat
the tire beads onto the wheel using the crowbar. 6. Reinflate the tire according
to the manufacturer's specifications,which can be found in the owner's manual.
7. Reprogram the ECU (Engine Control Unit) with the diagnostic tool using the
replacement TPMS's unique ID and its position on your car. This information
varies from model to model,but can found the sensor's service manual. The ECU is
generally found on the engine,though its exact location varies from model to
model.
